FAQ
What is Sol AI?
Sol AI is a place to chat with original AI characters who can remember you. You can start on the web, iPhone, or Android, and the same Sol account keeps your chats, memories, and plan together. The characters are fictional. Sol is for adults 18 and older, and you can start without a card.
Is Sol free?
Yes. Sol is free to start, and you do not need a card to open a chat. Free accounts can send 200 messages a day. Pro removes that daily cap and includes full memory history. Prices in the App Store, on Google Play and on the web can differ. Open the pricing page for the current list.
Can I use Sol in my browser?
Yes. You can chat in a mobile or desktop browser, and downloading an app is optional. This page sends browser chat to a featured character so the first screen stays fast. Voice calls on the web need Chrome, Edge, or Safari, and they need Pro. Notifications, the home-screen widget, and the lock-screen chapter countdown are in the iPhone and Android apps.
Do Sol characters remember me? (Can I edit what they remember?)
Characters can remember details you share, and you can open that memory and read it. You can correct a fact, pin one you want kept, or tell Sol to forget it. Free accounts keep essential memories. Full memory history comes with Pro. Sol does not promise to store every detail forever, and you choose what stays.
Does Sol have voice calls?
Yes. You can call a character and continue with the same memory as your chat. Calls are in the iPhone and Android apps. On the web, a call needs Chrome, Edge, or Safari and a Pro plan. It is the same character you were already talking with, heard out loud.
What are story chapters and the diary?
Some chats are scenes told in chapters. After a free account finishes a chapter, the next one opens 24 hours later. Pro can continue right away. The diary is a short note the character writes about your time together. You can read it from the character profile while that feature is switched on.
Is Sol for adults only?
Yes. Sol is for adults 18 and older. This site is a general overview and does not ask for your birth date. Confirming your age happens when you create an account in the app. Characters and their replies are fictional, and they are not medical, legal, financial, or other professional advice.
Is my chat private?
Your chats stay with your Sol account, and this public page does not display them. The privacy policy explains how Sol handles data. If something feels wrong, report it from the safety page or email support@solapp.ai. Sol AI is operated by Eros Media LLC.
